Fedora Still Needs Help Testing The New Zchunk Metadata Support

Filed under
Red Hat

Fedora has been working on transitioning to Zchunk for its DNF metadata due to its good compression ratio while being delta-friendly and leveraging the existing work of Zstandard and Zsync/casync. The metadata has been offered in Zchunk for some weeks while more client testing is needed before landing that support in Rawhide and in turn for Fedora 30.

The goal of this Zchunk metadata for Fedora is to speed-up DNF operations by needing to download less metadata. While the server bits are in place, additional client testing is desired before landing the updated packages in Fedora Rawhide where it will affect all users on this development build of Fedora ahead of the Fedora 30 release due out in the spring.

Systemd 241 Paired With Linux 4.19+ To Enable New Regular File & FIFO Protection

Filed under
Linux
Red Hat

The Linux 4.19 kernel brought the ability to disallow the opening of FIFOs and regular files not owned by the user in world-writable sticky directories in the name of security. Had this ability been around previously it could have prevented a number of CVEs going back a long time. In helping ensure this functionality gets utilized, Systemd 241 will now set these sysctl options to enable the behavior by default.

The restricted O_CREAT of FIFOs and regular files is not enforced by the kernel by default as it could be considered a breaking change but with systemd 241+ it sets the fs.protected_regular and fs.protected_fifos sysctls to enabled for having said functionality, similar to systemd's enforcing of hardlink/symlink protection. This protection is for avoiding unintentional writes to an attacker-controlled FIFO or regular file. That Linux 4.19 kernel commit notes at least a handful of security vulnerabilities that could have been prevented by this functionality with those CVEs going back to at least the year 2000.

Due to the recent unfortunate demise of a couple of my computers I found myself in need of a new laptop on rather short notice. I found an Acer Aspire 5 on sale at about half price here in Switzerland, so I picked one up. I have been installing a number of Linux distributions on it, with mostly positive results.

Fedora Decides To Not Allow SSPLv1 Licensed Software Into Its Repositories

Filed under

Server
OSS
Legal

Back in October, MongoDB announced the Server Side Public License v1 (SSPLv1) as their new license moving forward for this document-oriented database server over their existing AGPL code. SSPL was met with much controversy upon its unveiling and Fedora's legal team has now ruled it an invalid free software license for packaged software in its repositories.

The intent of MongoDB developing the Server Side Public License was to ensure that public cloud vendors and other companies using their software as a service are giving back to the community / the upstream project. SSPL v1 was based on the GPLv3 but lays clear that a company publicly offering the SSPL-licensed software as a service must in turn open-source their software that it uses to offer said service. That stipulation applies only to organizations making use of MongoDB for public software services.

Deepin Desktop Option Approved For Fedora 30

Filed under
Red Hat

Last month we mentioned that Fedora 30 was possibly picking up a Deepin Desktop Environment option for this Qt5-based desktop developed by the Deepin Linux distribution.

Assuming the packaging work remains in good shape, the Deepin desktop option will be found in the May release of Fedora 30. The Fedora Engineering and Steering Committee (FESCo) has formally approved of Deepin being offered by Fedora 30.

  • DevOps for the hybrid cloud: Red Hat Ansible Tower 3.4

    With the growth of the cloud and containers, DevOps has become increasingly important. Old-school sysadmin methods and means simply aren't up to managing server instances that can spin up at a moment's notice when needed. Red Hat knows that better than many companies, so its latest release, Red Hat Ansible Tower 3.4, goes even further in automating today's IT stack.

Security

While systemd 240 was released right before Christmas, it looks like systemd 241 will soon be released in order to address the recent "System Down" security vulnerabilities.

In case you missed it from earlier in the week, three vulnerabilities were discovered in systemd's journald: two memory corruption bugs and an information leak due to an out-of-bounds read. These vulnerabilities have been in systemd the past several years and and could enable a local root shell in a matter of minutes on i386 systems or in about an hour on x86_64. Well, except for the likes of Fedora and openSUSE systems that make use of GCC's stack clash protection. Details on those vulnerabilities via Qualys.

A new logo for the Fedora distro

Filed under
Red Hat

Let’s talk about the logo that the Fedora community is talking about and analyzing. I’m really too happy that the Fedora Project, one of my favorite Linux distro, is evaluating a new logo proposal.

Fedora was my first distro and I will undoubtedly be tied to her for the lifetime. It has served me faithfully every time on laptops, desktops, servers, and PIs. At this time, there are two proposals that have received greater care and interesting, they are further skimming and reworking of a long process to rebrand the old logo.

  • IBM Unveils Q System One Quantum Computer

    Quantum computing still seems like it comes from the pages of a science fiction novel, but it is slowly getting closer to being a commercial reality. At CES 2019, IBM Research has made what it hopes is a big step in that direction with what it calls the “first fully-integrated commercial quantum computer,” the Q System One. Existing quantum computers are confined to R&D labs, while the Q System One includes both the electronics and cooling components needed in a single package that was developed in concert with leading industrial designers. An extraordinary amount of cooling is needed to reduce qubit errors and reduce the need for additional qubits to be used for error correction.

    Usually, July is the month in where many interns go to ORNL to have real-world experiences in their fields. Some of them are students from schools, colleges, and universities and I had enough time to interact with most of them and to realize that some of them need more preparation in topics related to HPC such as Linux commands, HPC concepts, Programming, and Deep Learning.

15 Best Free Linux Wiki Engines

A wiki is a page or collection of Web pages designed to enable anyone who accesses it to contribute or modify content, using a simplified markup language. A Wiki engine is a type of collaborative software that runs a wiki system. This facilitates web pages being created and edited using a web browser. This type of software is usually implemented as an application server that runs on one or more web servers. The content is stored in a file system, and changes to the content are typically stored in a relational database management system (such as MySQL), although some simple wiki engines use text files instead. Wikis try to make it as simple as possible to write and share useful content, using intuitive page naming and text formatting conventions. Wikis are usually (but not always) wide open and assume a cooperating community. However, with spam bots prevalent, most wiki engines have lots of anti-spam measures such as page permissions, Access Control Lists, host blocking, blacklists, and CAPTCHAs in place. To provide an insight into the quality of software that is available, we have compiled a list of 15 high quality free Linux wiki engines. Hopefully, there will be something of interest for anyone who wishes to share information with others. Read more Also: Michal Čihař: translation-finder 1.1

Games: Stadia Scepticism, Epic, Linux Gaming Report and More

  • Stadia is about the future of YouTube, not gaming

    Yesterday, Google announced plans for a new game-streaming service called Stadia. Besides the logo, the controller, and a single game — Doom Eternal — the announcement left us with more questions than answers. Primary in my mind has been the query of why Google needs to be in the gaming business at all. Isn’t it enough to dominate web search, ads, and browsers, smartphone operating systems, and maps? What part of our lives does Google not want to know about? And then it dawned on me that we might be looking at it from the wrong perspective: what if Stadia isn’t a case of Google aggressively entering a new business sphere, but rather a defensive one to protect its existing kingdom?

  • Google Stadia's Grand Vision for Gaming Clashes With America's Shitty Internet

    Slow speeds, usage caps, and overage fees could mar the long-awaited arrival of game streams.

  • Slow Broadband, Usage Caps Could Mar Google Stadia's Game Streaming Ambitions
    I can remember being at E3 in 2000 and being pitched on the idea of a sort of "dumb terminal" for gaming. As in, you wouldn't need a computer or game console in your home, since all of the actual game processing would be accomplished in the cloud then streamed to your TV via broadband. Most of these early pitches never materialized. Initially because cloud computing simply wasn't fully baked yet, but also thanks to America' shoddy broadband. Cloud-based game streaming is something the industry has continued to push for, though nobody has yet to truly crack the market. Onlive probably tried the hardest, though again a lack of real cloud horsepower and sketchy residential broadband prevented the service from truly taking off. Undaunted, Google took to the stage at the Game Developers Conference to unveil Stadia, a looming game streaming platform that will let gamers play top-shelf games on any hardware with a Chrome browser. Google insists that the service, when it launches this summer, will be able to drive games at up to 4K resolution and 60 frames per second seamlessly between multiple devices with no need for game consoles, high-end PCs, loading times, or installs.

  • Epic Games CEO Tim Sweeney on PC store moderation: ‘We’re not in the porn business’

    Last year, Valve announced a hands-off approach to Steam that would allow anything onto the platform “except for things that we decide are illegal, or straight up trolling.” In addition to the Rape Day controversy, that policy has pushed Valve to take hardline stances on content revolving around child exploitation, school shootings, and most recently around tributes memorializing the New Zealand shooter. Sweeney, it seems, does not see the value it trying to protect content that pushes up against that amorphous line.

    Chasm, the crowdfunded adventure platformer continues to see great post-release support with the latest big free update out now. While it's not a personal favourite of mine (I much prefer Dead Cells honestly), it's still a reasonably good game overall. In fact, it's far better than a lot of action/adventure platformers and it does look great.
  • Counter-Strike: Global Offensive now has much better queue times for Danger Zone
    Following on from the tweak to Danger Zone to focus more on duos, Valve are still tweaking their Battle Royale mode in Counter-Strike: Global Offensive as well as the game as a whole. Firstly, for Danger Zone you should now see much better queue times for matchmaking. Before this patch, I could easily see queue times around 3 to 5 minutes (often the latter) even with a lot of people online which is not ideal and frankly that makes me (and no doubt others) get bored and look to play something else. Since this patch has dropped, I've played a good 30-40 matches and not a single one has hit even 2 minutes queue time (under 1 minute mostly now!) which is a pretty huge improvement.

LibreOffice 6.2.2 Office Suite Released with More Than 50 Fixes, Download Now

While LibreOffice 6.1 is still the recommended version for those who want a more stable and well-tested LibreOffice office suite, LibreOffice 6.2.2 is here for technology enthusiasts and early adopters who want to get a taste of the latest new features and innovations in the free and open-source office suite used by millions of computer users worldwide. "LibreOffice 6.2.2 represents the bleeding edge in term of features for open source office suites, and as such is not optimized for enterprise-class deployments, where features are less important than robustness. Users wanting a more mature version can download LibreOffice 6.1.5, which includes some months of back-ported fixes.," said Italo Vignoli. Read more
